This lets you restack a window above or below a specified sibling.
At least eclipse wants this functionallity.

* @above: a boolean
*
* Changes the position of @window in the Z-order (stacking order), so that
* it is above @sibling (if @above is %TRUE) or below @sibling (if @above is
* %FALSE).
*
* If @sibling is %NULL, then this either raises (if @above is %TRUE) or
* lowers the window.
*
* If @window is a toplevel, the window manager may choose to deny the
* request to move the window in the Z-order, gdk_window_restack() only
* requests the restack, does not guarantee it.
